MACHINE FOR BALLING CORD OR YARN.

SPECIFICATON forming part of Letters Patent No. 389,054, dated September 1888. Application tiled January 3, 1888. Serial No. 259,728. (No model.)

To all whom it may concern:

Be it known that I, SAMUEL BROWN, of Seaford Hundred, in the county of Sussex and State of Delaware, have invented a new and useful Improvement in Machines for Balling Cord or Yarn; and I do hereby declare that the following is a fnll,clear, and exact description of the same.

The object of the invention described herexo inaftcr is the production of a machine for balliug into solid and perfectly spherical form cord or yarn to be employed in the manufacture of baseballs, or for other purposes, such as for use in stores or the like. This machine i 5 is designed to carry out in a practical manner a certain method of winding the yarn,such as is described and claimed by me in an application filed June 14, 1888, Serial No. 277,127.

The invention consists, broadly, of holders for the balls having the necessary movements to secure the perfect formation of the ball; also in rollers i'or holding the ball having rotary and reciprocating movement,said rollers being combined with the other portion of the holder.

Further, the invention consists of a pressure-roller for holding the ball by its upper periphery and for applying tension to the yarn as it is fed under said roller to the ball.

Further, the invention consists in the employment of holding` means having reciprocating movement, and in means whereby the same is interrupted at certain intervals. Further, of the supports having rotany and lateral movements and of means combined therewith for automatically changing said lateral movement as the ball increases in size; also, in means of adjustment whereby the initial speed of the lateral movement to which the ball is subjected may be determined and varied at will.

Further, my invention consists in automatic means whereby the machine is stopped when the ball reaches a predetermined size; also, in means whereby the size of the space within the holder is automatically and proportionately increased as the ball attains greater size; and, finally, my invention consists in certain means of adjustment and in the various devices and combinations thereof which aid me in embodying the invention in a practicallyoperating machine.

In the drawings, Figure 1 is a perspective view of a portion of' the machine, illustrating the balls in position, the supports and holders for the same, and the devices in immediate connection therewith. Fig. 2is a front view of the entire machine, a portion of the frame being shown in section. Fig. 3 is a plan view of the upper portion of the machine. Fig. 4 is a vertical section through the machine. Fig. is a rear View showing a modification ofthe means for driving the operating-cam and for changing the speed thereof. Fig. 6 is a plan view of a section on line .fr of Fig. 5. Fig. 7 is a view of the cam-groove which reciprocates the ball-holders.

In Fig. 1 the position of the balls during their manufacture is shown at A A. They are supported by rollers B B', which are placed side by side with their axes parallel, and are arranged normally at a sucient distance apart to receive and hold in the intervening space the cores of rubber or other material upon which the Winding is done. The forward roller has its bearings in the side standards,1 1 ,upon the table,and the roller B is journaled in the upper ends of movable arms 2 2,hereinl after referred to. Each roll is adapted to have longitudinal reciprocating movement, and in the operation of the machine they are given both a rotary and a reciprocating :motion. They are both, also, provided with roughened surfaces, so that their movements Will be given the balls. Over the rollers and in a plane with the space between them the holders E for the balls are positioned, their purpose being to hold the balls from lateral movement, but allow them to receive the full action of the supporting and winding rolls B B', and at the same time to rotate freely under said action. These holders consist of small friction-wheels having concave peripheries carried in the forward end of a movable arm,E,which is in turn mounted upon a shaft, E, extending between the side standards. The yarn or material to be ballcd is drawn from any suitable supply, and is led throughV a guide and tension device, e, hereinafter described, and thence through a guide, 8, imme- IOO rotates the balls laterally .and constantly changes the course of the yarn or cord, is intermittent or irregular, being interrupted byY pauses7 at certain intervals. These pauses are slight, but in their periods of duration the yarn winds straight partially about the ball and in the same plane in which the yarn is fed. These periods in which the balls simply rotate are succeeded by the reciprocations, thus altering entirely the lateral position of the ball, (in respect to the point of feed,) which revolving continuously draws the yarn and causes it to be laid in a diagonal course until the recurrence of another pause, when the action of winding straight is repeated, the lateral shift or rotation of the ball being effected at each reciprocation. This peculiar combination of movements produces a perfectly round ball. The rotary movement is imparted to said rolls through the media of the sprocket-wheels 3 3 upon their ends, the sprockets 4 4 on the main driving-shaft C,and the intermediate chains, 5 5. A cam is employed to secure the desired reciprocating motion of the rollers (this being shown at D) on the supplemental shaft a. This cam operates, through an arm, b, a rock-shaft, c,which is pro# vided with a slotted arm, c5, extending to the rear. An arm, o, secured rigidly to the under side of the sleeve p in the shaft of the roller B, extends to within the line of the slotin the arm c5, and a projecting pin in the arm o enters said slot, asshown. The arm ois supported byarest extending from the post surrounding the rockshaft directly beneath the slotted arm. The

, movement of the rock-shaft is thus imparted to the roller B through the rigid arm o, and as the connection with the slotted arm c5 is a movable one the movement rearward of the roller C is not only permittedby the connection, but the amount of reciprocation of the roller is increased as the stud on the arm o approaches the end of the slot, for a purpose hereinafter to be described. On the upper end of the rock-shaft a cross-bar is pivoted, forming projecting arms 6 6, extending upon either side of the center. Between these arms and sleeves on the roller-shafts are pivoted links 7 7, connecting the two, and through this connection the reciprocation of the roller B is effected and governed by the movement ofthe stud ofthe arm o in the slot of the arm c5 through the roller B. The cam consists of The form of said groove is irregular, as in Fig. 7,.to give the desiredirregularities in the reciprocation of the rollers; but in general outline it is zigzag. At regular intervals one of the inclined portions is broken by a straight section of groove, and it is while the arm of the rollerb is at this point that the pause in the reciprocation of the rolls takes place.

In practice the operator takes a ball of small size, preferably composed of rubber, as a core, and after placing theend of the yarn thereon he wraps the yarn several times about the core to keep it in place, and then he positions it properly within the holders and the rollers B B. It will be obvious that the rate of rotation ol' the ball at this period of its manufacture must be the greatest, the speed being gradually reduced asthe ball grows larger by reason of the continuous increase of surface acted upon by the rollers. In view of this fact it is necessary, also, correspondingly and automatically to change the speed of the cam for operating the rolls longitudinally, its greatest speed being attained when the ball is started and gradually lessened in proportion to the growth of the ball. lt will be clear that the changein the course of the yarn, or, in other words, the lateral shift of the ball, must be proportionate to its rotary speed, as, should the ball remain in one position too long, the yarn would pile up in one course and either slip off or produce irregularities in the surface. The variable mechanism for accomplishing this automatic change in thespeed of the cam is now to be described.

Upon the driving-shaft C of the machine are l splined two beveled frictional wheels, g g, which are thus given rotary movement from vthe shaft, at the same time being permitted longitudinal movement thereon. Above these and arranged to bear upon them are two smaller beveled friction-wheels, g2, which are carried on a shaft, 13, in the free and rear end of a movable frame, g, pivotally supported upon the same shaft a. This shaft 13 also ear` ries a pinion, i, which, through the intermediate gear and pinion, z" fi, communicates the movement of the friction-wheels to a gear, h, which being mounted upon the cam shaft drives said shaft and cam. The whole frame g,with the driving mechanism carried thereby, is obviously adapted to be moved pivotally on the shaft a up and down, thus deriving more or less of the motion of the large frictionwheels,according as the position of said frame be at the periphery or near the center of rotation thereof.

The position of the frame with its frictionrollers g2 is determined and the movement thereof is controlled by the position and movement of the movable arm E, which carries the holders. Thus when the action is just starting the arm E, with the ball-holders, being in its lowest position, the frame operated by the intermittent connection will be in its highest p0- sition, and consequently the maximum speed is drawn from the large frictionwheels,and is imparted to the cam to change with the great- IOO IIS

IZO

38ans@ est rapidity the lateral shift of the ball, and consequently the course of the yarn wound thereon. As the ball increases, the arm moves upwardly, and through the proper connections the frame is moved toward the center of rotation, in this way gradually decreasing the speed of the cam and causing the lateral rotation or shift of the ball to be carried on with decreasing rapidity. The frame g is supported by means of a rack -bar, F, which has at its lower end a yoke engaging on either side with a slot in the side of the said frame, as at 14, Fig. 4. through the table,and at its upper end engages with a gear, k, on the shaft G. Upon the other end of the shaft is a pinion, k', which derives its motion from a segrnentel rack, It, operated by shaft E, which is itself actuated by the movable arm E. As shown in sectional view, upward movement of the arm E', on account ot' the growth of the ball, causes the segmental rack to move toward the front of the machine, rotating the shaft and depressing the rack-bar with the frame and frictional driving-wheels.

I have provided an adjustment between the movable arm E and the frame g', so that the position of the latter relatively to that of the former may be changed, in order that theinitial speed ot' the cams rotation may be accurately adjusted for the purpose of securing exactly the required reeiproeation of the rolls, andthe consequent lateral shift orrotation of theballs. This adjustment is shown in Figs. 1, 3, 4, and consists in means of altering the position of the segmental rack 7a2 on the shaft E. The rack is loose upon the shaft, and at its side is fixed rigidly an arm, H, secured by asuitable set-screw. The outer end of said arm is formed on a curve struck from the center of the supporting shaft, and is provided with teeth adapted to engage with a worm, Z, on a shaft, Z', mounted in suitable ears on the segmental rackarm- The outer end of the shaft Z is provided with a thumb-wheel, by which Ait may be turned. The two arms (segmental rack and arm H) are held against lateral displacement by means of a headed bolt in the former passing through the slot 15 in the latter, Fig. 4. The worm and teeth on the respective arms serve to lock them rigidly together, so that the movement of the shaft E is imparted to the rack-arm, as would he the ease were it fixed rigidly thereto. By turning the thumb-wheel either way the segmental rack will be moved, which motion will be imparted to the vertical rack-bar F through the intermediate pinion, shaft, and gear, thus effecting the desired change in the position oi' the small frictionwheels g', the arm H. shaft E, movable arm E', and holders remaining during this adjustment in stationary position. As before stated, the large friction-wheels on the main shaft have sliding as well as rotary movement thereon, and it is necessary to provide means for returning them to their normal position after they have been forced apart by the depression of the small friction-wheels, and also The rack-bar extends upwardly to give them a degree of resistance against the tendency of said wheels to force them outward sufeient to create strong frietional Contact between them, and thus insure the full transmittal of the motion. For these purposes bellcrank levers I I are provided, pivoted to the frame, the vertical arms of which extend to a point just in rear of the driving frictional wheels, their ends being bfureated to embrace the shaf t and bear upon collars combined with said wheels. rlhe horizontal arms extend toward each other, and are each connected with the ends of a band or rope which passes under pulleys 16 16, positioned on the frame at a point below the pivot-point of the bell-crank arms. From these pulleys the rope passes over the sheaves 47, located at the upper part of the machine-frame, and thence it extends downward in loop form and under a movable sheave, 17. This sheave is journaled in the forked upper part of a bar, m, which has a screw-threaded lower portion, to which is attached the npperpart of astrong spiral spring, J. The spiral spring exerts its force upon the pulley 17 and looped rope, tending to pull them downward, and this force is transmitted through the rope to the bell-crank levers, exerting a downward pull upon the horizontal ends and tending to force their vertical arms inward. This arrangement opposes the outward movement of the large frictionwheels and causes them to bear hard upon the small wheels,inaking operativefrictional contact and forcing them to their normal position for the formation of a new ball. The tension of the spring may be adjusted by means of the nut 19 to vary the resistance to which the movement of the large friction-wheels is subjected. Another desirable result-is obtained by this arrangement in that the pressure upon the ball may be regulated at will by changing the tension of the spring.

It will be observed that the movement of the arm E', with the ball-holders, will be more or -less free in proportion to the ease with which the frame g', with the small friction-rolls, is depressed and the freedom of this movement, depending as it does upon the amount of resistance placed upon the large frictionwheels, it will be clear that by the adjustment of the spring the movement of the arm E will be correspondinglyaliected and the ball in its growth will be subjected to more or less pressure. As shown in Figs. 3 and 4, a pivoted bar, 20, may also be used in connection with the pulley 17, it being provided with an adjustable weight. This bar may act in connection with the spring. The pressure required to force the large bevelgears apart varies with the position of the small wheels, and this variable pressure is secured by the spring. A weight, 2l, may be employed to act upon the pivoted frame carrying the small frietionwheels and the train of gearing, its otliee being to insure 'contact between the said wheels and the driving-` wheels.

As the ball being made grows in size, it is IOS vnecessary to enlarge the space within the hold- It `has been seen howk ing means therefor. that a portion of the ball-holder which is caris given a movement to enlarge .the space ini, proportion to the growth of the ball, and also to furnish a proper support for the same.

yThe rear roller, B', is therefore mounted in movable arms 2 2, carried by the rock-shaft n, extendingbetweenthesidestandards. From about the center of said shaft an arm, n', pro-2 -jeets rearwardly and connects through a link,?

22, with a projection, a2, of the movable arml E', so that the movement of the roller B toi separate the parts of the holder is controlled :by the movement of the arm E', which in turn is positively operated by the growth of theg` ball. By this arrangement the separation of the ball-holder depends directly upon the eny y largement ofthe ball itself, and the various ated upon.

`portions of said holder must always hear the proper relation to each other,whatever the size 4of the ball. `thatthe small friction-holdersE will be di- The arrangement of parts is such,

rectly over the center of the b all, and to sev cure this result the pivot-point of the movable arm is arranged to be in the same horizontal;

.i plane with the top of the core when thelatter"v is positioned, and as the ball increases and itsy center changes the holders E, besides havingl an upward movement, have aslight movement lto the rear to correspond with said changed pendently of the arm E', to enable the operator to remove completed ballsand to place in position the cores or smaller balls to be oper- In order to hold the yoke and frictionfwheels E in their lower position, a spring catch-lever, ll, is provided pivoted on theoperating-lever f, its rear end having a stud adapted to pass through said lever ,and engage with the lower end of a stop-screw, 12, supported in a small bracket on the forward end of the movable arm. When the operating-lever is down, the spring catch-lever holds -the friction-wheels in the required position,

cating movement; but as the pin of the arm o K this may be varied at will.

is moved away from the center ofthe rockshaft the stroke imparted thereto is greater, which thus increases the reciprocation of the rollers, which increase is necessary as the balls increase in size.

The machine is stopped automatically when the ball reaches a predetermined size, and I utilize the movement of the arm E for attaining this end. The beltshipper rod r, Figs. 2 and 4, extends across the machine and has bearings in the frame. Itis under tension applied kby a suitable weight, 2l, or spring,through the medium of a rope extending over a suitable pulley, and the tendency of this arrangement is to move said rod and ship the belt from the fast pulley to the loose pulley 26.l It is held in opposition to the action of the weight during the timeit is desired that the machine shall operate by means of a catchlever, S,piv oted to a standard, s', supported on the frame. The rear end of this lever has vertical movement and bears upon the under side of the shipper-rod, and is thus adapted to engage with a lug, 28, thereon and to hold the rod, as shown in Fig. 2, so that the belt will be on the fast pulley. In order to release this catch-,lever automatically `upon the completion of the ball, Iprovide a rod, K, extending from the forward end of the movable arm E to the lower part of the machine frame, passing in close proximity to the forward end of the lever S. At a point on the rod K below the forward end of said lever I tixadjustably a collar, 26, and

,it will be obvious that when the rod K is lifted it draws up the collar 26 and raises the forward end of the lever S, thus releasing the rear end from the lug28 and allowing the weightto exert its force and ship the belt. The size of the ball or the point at which the belt will be thrown is determined bythe ,position of the collar 26 in relation to the catch-lever, and One side of the lug 28 is beveled to allow the rod-to pass the catchlever when retracted to start the machine, and

.for securing this action a treadle, y29, is provided within easy reach of theattendants foot, and connection is made from this treadle to the rod by means of link 30 and bell-crank lever 3l.

As shown in dotted lines, Fig, 2, a weighted lever, Q, may be utilized to give any desired Weight to then movable arm E with the ballholder E, the bar being pivoted at one side of the frame and having its free portion resting upon a pin secured to the vertical rod K.

I do not wish to limit myself to the precise form of holders for the balls shown, as the fundamental principle of my invention may be carried out by different styles, it being essential, however, that the ball be given a variety l OO of movements, that it be held by its periphery,

the cam,in which the friction-wheels and other elements heretofore described are dispensed with. In this form of apparatus I employ two drums for transmitting the motion from the driving-shaft,said dru msbeing beveled or coneshaped and positioned parallel, but reversely. The one, L, is xed to the driving-shaft and transmits the movement through a belt to the other drum, L, xed to a shaft, t, journaledin hangers from the under side of the machine. A train of gearing, 30 3l 32 33, communicates the motion of this drum to the cam, as shown in Fig. 6. To effect the desired change in speed, the belt 34c is shifted laterally from one point on the drums to another,and this is done by the 'movement of the arm E', as follows: The belt-shifter consists of asleeve, u., adapted to slide on a supporting-bar, a', and having studs u2 projecting upward and downward from said sleeve and upon either side of the belt, each stud being provided with a small roller arranged to bear upon the edges of the belt. At opposite ends of the sliding sleeve the ends of asprocket chain or belt, a3, are secured, the chain passing around suitable sprocket-\vlieels, 35 35, upon either side of the machineframe, and also about a segmental sprocket-wheel, M. This segmental sprocket is carried by an upright shaft, N, journaled in the frame, and having at its upper end a pinion, 72', positioned directly under the machinetable. NVith this pinion asliding rack-bar,o, engages, the latter being held in suitable guides, 36, on the Linder side of the table. The' movable arm E is provided with a downwardly-extending arm, O, projecting through the machinetable and having connection at its lower end with the sliding rack by alinlr,37.

It will be obvious that as the arm E moves upward by reason of the increasing size of the ball the sliding rack and pinion will be operated, and this movement will, through the vertical shaft and segmental rack, move the sprocket` chain, which will slide the sleeve, and thus shift the belt to decrease the speed.

In the drawings three holders are shown, and this is a convenient number for a machine; but this number is not material and may be changed.

The tension devices consist of an arm, c, under spring-tension and pivoted to a standard, el, both parts having notched upper ends, through which the yarn is lead. In order to stop the machine by hand, a rod, x, is provided, as in Fig'. 4, connected with the shipper-rod catch S and extending up through the table at the front of the machine.
